Abstract (en)

Drawing gripper for weaving looms comprising a gripping device of the weft thread consisting of the coupling between a fixed surface formed in the inner part of the gripper hook and inclined with respect to the shifting direction of the gripper, and the mobile surface of a wedge carried on the front end of a longitudinal rod housed in the gripper and movable in an axial direction with respect thereto. The movable rod is driven in an open position of the gripping device, in contrast with spring means provided on the gripper, by lever means cooperating with fixed outer abutments arranged on the loom, and on the same rod the rear portion of a flexible metal plate is attached, the free front portion whereof imparts an elastic pressure force to the upper edge of at least one of the cooperating surfaces of said gripping device.
